General
The SPL-D2 is a decibel meter. It can be used as a stand-alone device or combined with a DateQ SPL-5 limiter. The display is made of high-efficiency bi-colour LEDs, making it clearly legible, even from a distance. When the pre-set dB is surpassed, the LED colour turns red, quickly showing you whether the sound is too loud. Combined with the SPL-5, this is a professional sound limiter that both warns and sanctions, nipping excessive sound levels in the bud.
DateQ SPL-D2: stand alone
When you use the SPL-D2 separately, you connect the included microphone and mount it to a fixed point, after which the measured levels appear on the display. The included software allows you to set the maximum sound pressure level. Should it be surpassed, the digits light up red, serving as an optical warning for bands and DJs, for instance. There are three measuring curves: ANSI-A, ANSI-B and ANSI-C. Naturally, to be absolutely certain, you can optimally calibrate the microphone. The display is automatically dimmable, dependent on how much light is around it. A professional audio tool.
